These are special lenses designed for APS-C size sensors so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!

Overview

The Sigma 10-20mm 4-5.6 EX DC is an ultra wide angle lens designed for APS-C digital SLRs. This wide angle zoom lens is perfect for a variety of subjects including landscape photography, event photography, cityscape photography, interior photography, architecture photography or anything that needs the 102º angle of view that this lens offers. Outstanding image quality and a premium build make this lens a unique tool in a photographer’s kit.

I love landscape photography, using every spare minute I have I try to capture the beauty that we all too often take for granted. This image was taken using my favourite Wide Angle Lens, the Sigma 10-20mm.

Inspiration/Description:

Waterfalls along the Columbia River Gorge amaze visitors year after year. The hanging valley walls from Portland to the east provide one breath-taking view after another. In the fall, Latourelle Falls is ablaze not only with colorful foliage but also spectacular yellow lichens, which grow on the surrounding cliffs. A slow shutter speed allowed my SD1 to capture the creamy flow of water over the 249e plunge, and having the FOVEON sensor-equipped body anchored to my rock-solid Gitzo tripod allowed the camera to resolve unbelievable detail: If you zoom in on the image, you can see the hexagonal shapes comprising rocks face, evidence of volcanic formation. The large crystals formed through slow cooling.

Inspiration/Description:

Eagle Cliff Falls in Havana Glen Park, Montour Falls, New York, is one of the most picturesque waterfalls I have photographed. Inside an incredible amphitheater of siltstone, McClure Creek plunges over a forty foot drop and then swirls gracefully as it makes it way down to a narrow glen (which begins right behind where this picture was taken). Two neutral density filters reduced the light to allow the bubbles to swirl. An additional polarizer filter cut more light and intensified the fall colors. This HDR image was produced from a single exposure processed at 4 exposure settings in Adobe Camera Raw (-2; -1; 0; 1) and then combined in Photomatix Pro 3.2.

Periodic burning is the recipe for keeping indigenous species prospering, driving out the succession of woodland species. A super wide angle of view allows the sunflower blossom, positioned about 18? from the front of the lens, to dominate while showing the delicate array of grasses and wildflowers surrounding the yellow bloom.

I believe that the Ithaca / Watkins Glen area of New York has the greatest concentration of sizable (and picturesque) waterfalls per square mile of anywhere in the United States. In the upper gorge of Buttermilk Falls State Park, water drops twenty-five feet over several shelves before swirling below. A Sigma circular polarizing filter, a steady Gitzo tripod, and a remote trigger produced tack sharp rocks yet oh-so creamy water patterns. Most time exposures of waterfalls use shutter speeds between, say, 1/4 second to a about two seconds. In this case I chose to really build the softness of the cascades and smoothly depict the white eye of the whirlpool below, so I left the shutter open on this dimly lit morning for almost a half a minute.
